IBM RS/6000 44P - Manual (Page 160)

When the service aid is running from stand alone diagnostics, the flash-update image
file is copied to the file system from diskette. The user needs to provide the image on a
diskette since the user does not have access to remote file systems or any other files
that are on the system. If enough space is not available, an error is reported stating
additional system memory is needed. After the file is copied, a warning screen asks for
confirmation to continue the update flash. Continuing the update flash reboots the
system. The current flash image is not saved.
The update_flash command can be used in place of this service aid. It is located in the
/usr/lpp/diagnostics/bin directory.
Attention: The update_flash command reboots the entire system. Do not use this
command if more than one user is logged in to the system.
Update System Flash
Note: This service aid runs on RSPC (Power PC Reference Platform) system units
only.
This selection updates the system flash for RSPC systems.
The user provides a valid binary image either on diskette or from a qualified path name.
The diskettes can be in DOS or in a backup format.
The flash-update image is copied to the /var file system. If there is not enough space in
the file system for the flash update image file, an error is reported. If this occurs,
increase the file size of the /var file system. The current flash image is not saved. The
command automatically removes the /var/update_flash_image file.
After user confirmation, the command reboots the system twice to complete the flash
update.
